The shrewd and capable career elite Lei Li, the gentle and beautiful full-time housewife Ren Duomei, and the invisible rich girl Shen Jianan who strives to prove herself, originally of different ages, different personalities, and no intersection of experiences, but they became close friends who knew each other and loved each other at an important node in their lives when facing difficulties in the workplace and life. From speculating about each other to gradually accepting each other, from facing it alone to opening their hearts to each other, from fighting alone to supporting each other, the three brave, strong, wise and powerful modern urban women finally worked together to solve the various problems and confusions in each other's lives, and witnessed each other's growth and transformation. After going through thousands of sails, the three people, with their own efforts, not only tore off the inherent labels attached to women by the outside world, but also bravely opened up a career of self-realization, just like three different tunes of music intertwined together to play a wonderful life music.
